NON-REFILLABLE BOTTLE.

To all whom t may concern.'

Be it known that I, GEORGE A. PORTER, a citizen of the United States,and a resident of Boston, in the county of Suffolk and Commonwealth oflVIassachusetts, have invented certain new and useful ImprovementsinNon-Refillable Bottles, of which the following is a full,`clear, andexact specification.

The object of this invention is the construction of an improved devicedisposed for being secured within the neck of a bottle to prevent thelatters being refilled, the objects sought being bothsimplicity ofparts, economy in manufacture and certainty in operation.

Referring to the drawings forming part of this specification, Figure 1is a vertical central section of the upper part of a bottle containingmy improved device. Fig. 2 is a side elevation of said device, but withthe members composing it slightly separated. Fig. 3 is a longitudinalsection of the device and bottle showing how the device automaticallycloses when in a substantially horizontal position. Fig. el is a planview of one of the members composing the device. Fig. 5 isl alongitudinal section of the device and bottle neck showing the sameinverted.

The reference numeral 1 designates the neck of a bottle of substantiallyusual form, practically the only difference over bottles now in useconsisting of a shoulder, or projections, 2 within the neck near itsjuncture with the body of the bottle.

The bottle stopping device comprises five parts, three of which composethe case or stationary parts, and the other two being the movablemembers. The latter members consist of the valve and the valve-closer.

Said stationary parts consist of three cylindrical members or sections,the lowermost one of which is numbered 3 and carries the valve openingand seat 4. The intermediate member or section 5 is an inverted cuphaving its walls internally oblique, at an angle of preferably aboutthirty degrees, with several vertical holes or channels 6 openingthrough the walls to the upper' surface 7.

The uppermost member or section 9 is formed with a mouth 10 forreceiving a cork or like means of closure, the bottom 11 thereof havinga centrally located pouring hole 12 through it. This hole is made slnallSpecification of Letters Patent.

enough in diameter to cause the bottom 1l to act as a shield forpreventing the introduction of a wire or like instrumentality throughthe hole 12 and one of the channels 6, and thence down into engagementwith the valve.

Said three sections are formed with mutually engaging seats and flanges13 which are preferably cemented together before the same are put intoplace, and a supply of cement is also applied between the same and theinterior of the bottle neck, particularly between the two ribs 11 on thesection 9. This not only fastens the device in place, but preventsleakage between the same and the interior of the neck.

Through the hole or valve opening l projects the stem 1G of a loosevalve 15, the latter being designed to rest upon the valve seat et andclose the opening against the admission of any liquid to the bottle. Thestem is a truncated cone in general shape, but with its lateral surfaceconcaved, its largest diameter loosely fitting the opening a. Above thevalve and resting thereon when the bottle is not in an invertedposition, is a ball 17 of some comparatively heavy material, as metal,glass or the like, and serving to insure the liquid-tightness of thevalves seating.

lVhen the bottle is turned upon its side, the ball rests upon theinclined surface S and rolls against the valve 15 with sufficientpressure to hold the latter tightagainst the seat l. In practice, it isfound that the body of the bottle can be elevated until its lowermostpoint is at the level of the valve opening, and the ball will still actagainst the valve hard enough to keep it closed.

lVhen the bottle has been tipped until the ball 17 leaves the valve,even until the bottle is entirely upside down, the ball cannot close thechannels G and in any perceptible Inanner interfere with the out-flow ofthe bottles contents. This is clearly evident in Fig. 5.

As shown in the drawings, the upper surface of the section 5 closebeside its flange 13 and comprising the areal penetrated by the channels6, is outwardly depressed or made flatly conical. The object of this isto further prevent the introduction of a Wire through the hole 12 andone of the conduits or channels 6, and thence down to a point `where itmight engage and hold the valve in an open position. With a suitablyflexible Wire, the outermost surface of one of the channels might be metby the end of' the wireintroduced'atan angle through the hole l2, and bypressure the Wire be pushed` down through such channel; but, bycharnfering said area as described, the Wire-end cannot engage theoutermost surface of a channel, butl will meet the flange 13v and theslight shoulder or ledge between it and aI channel. This renders itpractically impossibleA to, Work a Wire down into engagement with the,valve.

The valve itself is composed of a comparatively light material, in orderthat, in CaSe the vacuum method of filling is attempted, the inrush ofthe liquid will loat the valve up into contact with the valve-seat andthereby eectually prevent further reception of the fluid.

What I claim is:

A device for rendering bottles non-refilla'ble, comprising a chamberedmember secured in the neck of the bottle for which it is designed andhaving a central opening communicating with the bottle, a gravity valveforA closingy said opening, a member spaced from.. said ichamfloeredmember nearer the mouth of the bottle and having a central opening, theroof of said chambered member being centrally flat and transverse to theaxis of' the bottle neck, an annular space about said. flat. spacel'approximating a frustum of a cone, anda plurality of holes passingthrough saidannular spaceparallelwith axis.V of7 the bottle neck intovthe space Within thechambered membensaid annular space beingy slightlyprolongedbeyond the circle of saidv holes, Wherebyfa Wire is hinderedfrom entering said holes fromA the central opening above.

In testimony that .I claim the foregoing inventiom Il have hereunto setmy hand this 7th. day, of October, 1915,
